Where's the love? Two guys almost come to blows over JoJo Fletcher in The Bachelorette's Monday, May 30, episode.

The ABC dating series' preview clip shows Alex, a 25-year-old U.S. Marine, telling Chad, a 28-year-old luxury real estate agent, to stop keeping tabs on the Bachelorette while she's spending time with other guys.

"She's probably getting creeped out," Alex tells his fellow contestant. "It's getting weird that you just are hanging around, lurking around the corner."

Chad doesn't appreciate the feedback and fires back with, "Yo, f--k you, for real. I'm serious. … Keep that up, you're gonna lose your damn teeth." Uh-oh! Where's former Bachelorette — and practicing dentist — Ashley Hebert when you need her?

Based on the season 12 premiere that aired Monday, May 23, Chad already appears positioned as this year's villain. In the episode, he mocked his competition and even made disparaging remarks about (gasp!) ex-Bachelor Ben Higgins.

Watch the tense scene unfold in the video above.

The Bachelorette airs on ABC Mondays at 8 p.m. ET.
